RESULTS. Cl~ removal from apical and basolateral surfaces produced cellular alkalinization (apical side, 0.07 pH units; basolateral side, 0.06 pH units; both sides, 0.20 pH units). Application of 100 /u,M H2-4,4'-diisothiocyanatodihydrostilbene-2,2'-disulfonic acid (DIDS), an anion exchange inhibitor, on the apical side produced an alkalinization (0.02 pH units) followed by acidification (—0.05 pH units), whereas basolateral H2DIDS caused a substantial acidification (—0.16 pH units). In the absence of Na, CP removal from the apical side caused a transient alkalinization (0.03 pH units) followed by a return to baseline; Cl~ removal from the basolateral side caused a small (—0.03) acidification. In Na-free Ringer, apical H2DIDS produced a transient alkalinization (0.02 pH units), whereas basolateral exposure had no effect. 5-Nitro-2-(3-phenylpropylamino)benzoic acid (NPPB), TV-phenylanthranilic acid (DPC), and niflumic acid (50-200 ptM), known Cl~ channel blockers, produced cellular acidification in control Ringer. Niflumic acid hyperpolarized Em and inhibited depolarization after Cl~ removal. Western blot analysis failed to detect AE2 expression in cultured BCECs. However, fresh BCECs produced a trace response.
